I made several hundred for my son's restaurant. I used natural colored lightweight cotton canvas, which will drape but will withstand the real test of time. I used my serger and made a rolled hem and made them each 19" square, which allowing for shrinkage still gives a good cover. Every time I use one (I kept some for myself) I get pleasure from the organic feel and the simplicity. Oh and I used Made in USA canvas. That was important to me.
